SPIKE OR FASTENING.

To all whom it may concern:

Be it known that I, LUCIAN J. I-IINE, a citlzen of the United States,residing at 'Vinston Salem, in the county of Forsyth and State of NorthCarolina, have invented a new and useful Spike or Fastening, of whichthe following is a specification.

The primary object of my invention is to produce a spike or fasteningwhich when driven into wood or similar material will fasten and securelyhold thereto a rail of iron or any other suitable material. This spikeor fastening may be in the form of an ordinary railway spike at the headand neck and throat for tting against the sides of the rail laid on andto be securely fastened to the cr0ss-tie and to be spiked thereto orother object to be fastened together. The shank of .the spike is twistedand triangular in cross sect-ion, thus giving to the spike a continuousbond to the wood into which it is driven and being triangular in formand twisted presents a continuous lever which operates against the sidesof the wood or other material into which it is driven, and therebyresists any effort to pull or jar the grip of the spike from the wood.

Figure l is a side elevation of the device and, Fig. 2 is a crosssection on line 2-2 of Fig. 1.

Referring to the drawing the letter A designates an L-shaped stem havinga twisted shank B of greater transverse diameter than said stem, theturns C and D of the shank being triangular in cross section toSpecification of Letters Patent.

secure a wedging action, thus to reduce resistance to entrance indriving the same into an object, and the two turns of the shankterminating in an entering point E of helical form.

The shank is tapered from the handle to near the point and is thenshaped into a pointed helical form. In addition to the tapering of theshank the same is formed substantially wedge-shaped in cross sectionwith each corner of the wedge chamfered so as to obviate all parts whichare liable to break, and to present a structure in which the resistanceto removal is emphasized.

Having described my invention, what I claim is:

l. A spike having an L-shaped stem and a twisted shank, the turns of theshank being triangular in cross section from the stem to the point tosecure resistance to extraction, and the turns of the shank terminatingin an entering point of helical form.

2. A spike formed with a Stem and a shank, the shank being bent at rightangles to the stem, and the shank formed substantially wedge-shaped incross section from the stem to substantially the point, the shank beingtwisted from the stem to the point and formed so that the meeting edgesat each corner are blunted.
